Reason for Recall

Cardiovascular Systems Inc. is recalling the WIRION system due to complaints of filter breakage during retrieval. Under certain circumstances, such as when the filter basket is too full, the filter assembly may become difficult to withdraw. In this situation, withdrawal may cause the WIRION system filter component to tear or separate, which may result in series adverse events such as embolization, need for additional medical procedures, or possibly death.

Cardiovascular Systems Inc. has received reports of nine device malfunctions and no reports of death related to this device issue.

Who May be Affected

Patients receiving atherectomy procedures where the WIRION system was used.
